Signs of Exhaust & Emissions Problems
These common symptoms often point to an issue with your vehicle’s exhaust system.
1. Loud Noises from Under the Car
A roaring sound that gets louder when you accelerate is the most common sign of a muffler or exhaust pipe leak. Hissing or tapping sounds can also indicate a leak from a gasket or manifold.
2. Check Engine Light is On
Many emissions-related components, like the catalytic converter and O2 sensors, will trigger the check engine light if they fail, often leading to a failed emissions test.
3. Reduced Fuel Efficiency
If your car’s computer gets bad data from a failing O2 sensor, it can cause the engine to use more fuel than necessary, hurting your gas mileage.
4. Smell of Rotten Eggs or Gas Fumes
A sulfur or “rotten egg” smell from the exhaust often indicates a failing catalytic converter. The smell of raw gasoline fumes in or around the car can signal a dangerous leak in the exhaust or fuel system.
